The flow-collecting groove of above-mentioned design is that then flowing in thimble inlet opening 511, that can consider thimble inlet opening 511 like this offers position in order to ensure that the current flowed at shell water inlet 11 obtain a convergence in flow-collecting groove;
The bottom surface of described thimble cap 51 is equal with the range ability of thimble rod 52 to extreme position to the distance of the cascaded surface of described inner core flowing hole 41, then when spring 6 is compressed, after thimble rod 52 inserts inner core delivery port 43, thimble cap 51 is connected on the cascaded surface of inner core flowing hole 41, and this cascaded surface is as a confined planes;
An inner core friction top 2 is connected in the bottom of shell water inlet 11, described inner core friction top 2 is also lined with inner core O type circle 3 with top shell 1 junction, the bottom outer wall of this inner core friction top 2 is connected and fixed by screw thread and inner core 4, this inner core friction top 2 also has a communicating passage run through 21, the top of described communicating passage 21 is communicated with shell water inlet 11, and its bottom is communicated with flow-collecting groove and this communicating passage 21 bottom width is less than the groove width of flow-collecting groove;
An inner core eddy flow passage is formed between the inner chamber of described top shell 1 and inner core 4 outer wall, the mode that the bottom of this top shell 1 is threaded connection and nut 7 are connected and fixed, this nut 7 has an insertion groove simultaneously, the bottom of described inner core 4 to be placed in this insertion groove and and form the nut eddy flow passage of ring-type between the inwall of this insertion groove, this nut eddy flow passage and described inner core eddy flow channel connection also form air swirl passage 72, the atomization mouth 71 that a width is greater than inner core delivery port 43 width is had in the bottom of described nut 7, this atomization mouth 71 is communicated with described inner core delivery port 43, the width of described atomization mouth 71 progressively increases along inner core delivery port 43 to the direction in its external world simultaneously,
In order to ensure that inner core 4 and nut 7 are better connected and fixed, a clamping cap 9 is also lined with bottom inner core 4 with bottom the insertion groove of nut 7, Packed inner core O type circle 3 is also padded in inner core friction top 2 and shell 1 junction simultaneously, and nut 7 and shell 1 junction are also lined with the nut O type circle 8 sealed;
Described top shell 1 sidewall has an air inlet 12, this air swirl passage 72 is in communication with the outside by described air inlet 12, outer wall bottom described inner core 4 is round table-like, and around this round platform lateral wall and along described inner core delivery port 43 the outside scattering in center and have several air swirl groove 45, described air swirl passage 72 is communicated with atomization mouth 71 by described air swirl groove 45, and the center line of described air swirl groove 45 and the centerlines of described air swirl passage 72 are acute angle simultaneously.
The top surface area S1 of thimble cap 51 is greater than the area S3 of the cascaded surface of thimble rod, as shown in Figure 5, in time calculating the pressure in inner core, pressure F=P*S2 suffered by thimble, P is now the pressure passing into current, and S2 is the lifting surface area by this pressure, when thimble rod 52 be in inner core conflux in 42 time, lifting surface area is S2=S1=π D
2/ 4 (S1 is the top surface area of thimble cap 51), and after thimble rod 52 is inserted into inner core delivery port 43, the lifting surface area of thimble 5 is then S2=S1-S3=(π D
2-π d
2)/4 (S3 is the base area of thimble rod 52).
At the equal conllinear of center line of the shell water inlet 11 be provided with, communicating passage 21, air swirl passage 72 and atomization mouth 71 for best.
The operation principle of the present embodiment:
Under non-water flowing state:
As shown in Figure 7, the thimble 5 be in the aerosol spray of original state makes its thimble rod 52 away from inner core delivery port 43 owing to being subject to the support force of spring 6, and the pressure that now end face of thimble cap 51 bears is specified pressure.
Under normal operating conditions:
As shown in Figure 6, A mouth is shell water inlet 11, B mouth is air inlet 12;
Current are flow in sprayer body by shell water inlet 11, and by communicating passage 21, thimble inlet opening 511, inner core flowing hole 41 and inner core busway 42, then flow out from inner core delivery port 43, meanwhile, compressed air is passed into from air inlet 12, compressed air is now combined with current by air swirl passage 72 and air swirl groove 45 and at atomization mouth 71 place and forms aerosol, finally spouting from atomization mouth 71.
As shown in Figure 8, thimble 5 in aerosol spray now gives it pressure owing to being subject to current is greater than specified pressure, so thimble cap 51 Compress Spring 6, namely thimble rod 52 is now inserted in inner core delivery port 43, current then flow out from the inner core delivery port 43 reduced, and then meet the requirement of aerosol spray to the current ejected.
Under enabling automatically cleaning state:
As shown in Figure 9, reduce the pressure passing into current gradually, so make its downward pressure acted on thimble cap 51 reduce, 6, spring is now replied gradually, thimble rod 52 also departs from inner core delivery port 43 gradually, inner core delivery port so now 43 can increase relative to the water-outlet area of the inner core delivery port 43 under duty, therefore can remain in the dirt removal at inner core delivery port 43 place and be discharged by atomization mouth 71.
This not only reduces the quality requirement of sprayer work water used from block clearing sprayer, also by controlling, water flow pressure can realize Long-distance Control blowdown, blowdown concentrated by many sprayers, when not dismantling sprayer, effectively cleaning blocks sprayer, reduce the probability of sprayer blocking, thus reduce maintenance cost.
The foregoing is only the preferred embodiment of the invention; not in order to limit the invention; within all spirit in the invention and principle, any amendment done, equivalent replacement, improvement etc., within the protection domain that all should be included in the invention.
